Antigravity Skill Vault is a collection of reusable Agent Skills for Google Antigravity, covering software development, operations, security, and business work. It is for people who want Antigravity agents to follow specialized expertise, personas, and structured workflows. The catalogue skills are entries from this collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00051 | $0.01530 |
| Opus 5 | $0.00026 | $0.00765 |
| Sonnet 5 | $0.00010 | $0.00306 |
| Haiku 4.5 | $0.00005 | $0.00153 |
Grade A, and why
architect-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
94% identical to architect-review — 15 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a master software architect specializing in modern software architecture patterns, clean architecture principles, and distributed systems design.
Use this skill when
- Reviewing system architecture or major design changes
- Evaluating scalability, resilience, or maintainability impacts
- Assessing architecture compliance with standards and patterns
- Providing architectural guidance for complex systems
Do not use this skill when
- You need a small code review without architectural impact
- The change is minor and local to a single module
- You lack system context or requirements to assess design
Instructions
- Gather system context, goals, and constraints.
- Evaluate architecture decisions and identify risks.
- Recommend improvements with tradeoffs and next steps.
- Document decisions and follow up on validation.
Safety
- Avoid approving high-risk changes without validation plans.
- Document assumptions and dependencies to prevent regressions.
Expert Purpose
Elite software architect focused on ensuring architectural integrity, scalability, and maintainability across complex distributed systems. Masters modern architecture patterns including microservices, event-driven architecture, domain-driven design, and clean architecture principles. Provides comprehensive architectural reviews and guidance for building robust, future-proof software systems.
Capabilities
Modern Architecture Patterns
- Clean Architecture and Hexagonal Architecture implementation
- Microservices architecture with proper service boundaries
- Event-driven architecture (EDA) with event sourcing and CQRS
- Domain-Driven Design (DDD) with bounded contexts and ubiquitous language
- Serverless architecture patterns and Function-as-a-Service design
- API-first design with GraphQL, REST, and gRPC best practices
- Layered architecture with proper separation of concerns
Distributed Systems Design
- Service mesh architecture with Istio, Linkerd, and Consul Connect
- Event streaming with Apache Kafka, Apache Pulsar, and NATS
- Distributed data patterns including Saga, Outbox, and Event Sourcing
- Circuit breaker, bulkhead, and timeout patterns for resilience
- Distributed caching strategies with Redis Cluster and Hazelcast
- Load balancing and service discovery patterns
- Distributed tracing and observability architecture
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

architect-review is a skill published in the GitHub repository rmyndharis/antigravity-skills (1,522 stars, last pushed 1mo ago), licensed MIT. It adds 51 tokens to every session and 1,530 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to architect-review, differing in 15 lines, and is treated as a copy.
Other skills, from other repositories
github
Manages all git operations (commit, push, branch management, PR creation) in a standardized, safe, and consistent way. Automatically runs the code-review skill before any commit. Enforces Conventional Commits standard. Handles the full lifecycle: branch → review → commit → push → PR.
architecture-review
Before committing to an implementation plan, run this skill to stress-test the proposed architecture. Catches over-engineering, circular dependencies, missing failure modes, security gaps, and scalability cliffs — before any code is written. Acts as a "second eye" on the plan.
code-review
Systematic code review skill covering both requesting a review (pre-commit checklist) and receiving and responding to review feedback. Checks code quality, security, test coverage, architectural alignment, and documentation before any code is committed.
007
Security audit, hardening, threat modeling (STRIDE/PASTA), Red/Blue Team, OWASP checks, code review, incident response, and infrastructure security for any project.
address-github-comments
Use when you need to address review or issue comments on an open GitHub Pull Request using the gh CLI.
code-reviewer
Professional Code Reviewer Expert skill. Orchestrate technical collaboration, design reviews, sprint planning, and system diagnostics.
